Forget sex, drugs and rock 'n' roll - Miley Cyrus is "all about Jesus."

The squeaky-clean Hannah Montana star, along with best buddy, Mandy Jiroux, get stuck into answering viewer questions during their latest YouTube installment of The Miley and Mandy Show.

But it's a question about whether the girls are Christians gets by far the most enthusiastic response.

“We love Jesus!" committed Christian Miley enthuses. "Jesus rocks! She dances for Jesus. I sing, dance and act for Jesus!...Now that I think about it, I do everything for Jesus.

“We make the YouTube videos for Jesus. We’re all about it."

The pals also reveal their favorite color (blue) and number of boyfriends they have (zero.)
